EFI Magnum and overdrive swap into a late-B...questions

The time has come, and Im going to do the EFI swap in my 78 Fury. The local Ecology has half price day every Tuesday and Thursday, so I can get a complete 5.9 Magnum and A500/518 trans out the door for under $200, complete with wiring harness and computer. I am no stranger to the wiring involved. My question is the trans. I heard somewhere that the floor doesnt have to be cut to fit the OD on a late-B. I know the trans crossmember has to be modified, but what about the torsion bar crossmember? I am planning on grabbing the whole setup out of a 94 or 95 to stay OBD1. Will the A518 fit, or am I stuck with the A500? Whats everyone runing for a fuel pump. I did a search, but only came up with rather vauge (generic) information. Any Magnum swappers out there?

I did the 98 and up swap but did not change out the trans.
the people had some hammering to do but they also cut off the webbing on the trans is my understanding.
Don't think the torson bar mounts were touched.

The fuel pump can go two ways I guess.
One guy cut out the one in the tank of the donor truck and mounted that in his tank.

I chose to run the summit msd pump and the areomotive regulator. This requires a return line whereas the stock does not.

What kind of car did you swap yours into? Did you have any issues running the 3 speed trans with an OBD2 setup? Im going OBD1 in mine. Now that you mention it, I do recall reading somewhere that the casting ribs had to be ground off in a few places

We did an OBDII swap (96 318) and 518 into an 84 Ramcharger. We had lots of room. It runs great except for some noise out of the alternator bearings.

I dropped it in a 65 coronet.
Didn't use the stock computer or wiring.
Got a one off painless harness and computer running mine.

wrote up about the swap here, and the odd things I had to do, as well as the different ps pumps etc.
It has fallen off the board, but is still on the coronet registry.

Not to hijack your thread, but how many of those 5.9/518 setups does ecology have? That sounds like a killer price.

518 and 500 are about the same in size externally, so you can use either one. The issue with the late b-bodies is the isolated torsion bar crossmember. I talked to one guy who did a 518 on a 73 charger, he got it to fit without modding the isolated torsion bar crossmember, but chopped the stock frame/ upper torsion bar crossmember. However since the 518 can be fit under a 71-72 B body torsion bar crossmember with some trimming of the ribs on the transmission, it's possible you may be able to get the 518 to squeeze between the upper torsion bar crossmember and the lower isolated torsion bar crossmember. On mine I am very much considering relocating the torsion bar hex sockets to the upper torsion bar crossmember and junking that isolated torsion bar crossmember. This will require going to teh 72 and prior t-bars but will get that pesky isolated t-bar crossmember out of the way and will allow me to install frame connectors.

They have quite a few. Its a good place to go on a Tuesday or Thursday, since those are the half price days every week. Ya still see A-bodies down there, but they get picked pretty quickly. Every now and again, ya see a b-body or two, even some C-bodies.
